Mineralized veins within a dunitic rock.  These can tell a geologist about the direction the rocks were shearing.
Looking down a fault; my Dad for scale.
Slickensided fault surfaces; geologists can use these to tell which way the fault moved
Looking across major fault that separates the gabbros (lower crust) of the eastern side from the ultramafic rocks (mantle rocks) of the west.  Fault runs along valley
View of the red hills of Leka
Looking down a fault plane on the western side of the island, fault and fault-deformed rocks in foreground
Maybe a pillow lava from Madsøya, but I am unsure
Metalliferous rock on Madsøya, described in Prestviks guide, right near pillow lava stop.
Transition from dunite (at bottom) to harzburgite (top, mottled texture)  This boundary is known as the petrologic MOHO and marks the transition from the tectonized peridotites rocks (the harzburgite) of the upper mantle with the dunites of the lowermost lower crust.
Contrast between yellow dunitic rocks and clinopyroxene rich rocks (the red ones).  Different compositions of the mineral olivine probably account for these differences in color.  (The red rocks have more iron and less magnesium when compared to the yellow rocks.)
